Espanyol Barcelona

Espanyol recently went on a seven-match unbeaten run in the league. Before that streak, the Catalans lost back-to-back matches at the beginning of the season and they have now lost their last two games as well. Those defeats, to Sporting Gijon and Getafe, have taken the shine off the club's promising form, and Mauricio Pochettino's side now faces a tough trip to struggling Atletico Madrid on Sunday. The Barcelona-based side has dropped to 10th place in the table and striker Jose Callejon admits the players are concerned. "We are a little bit worried about our last two results - we need to get back to winning ways as soon as possible," he said. Fernando Marques and Ivan De La Pena could return on Sunday, but Ferran Corominas remains sidelined.
